BOND
BOND is a San Francisco startup building Donna, an AI Chief of Staff for CEOs, founders and busy executives. Donna plugs into the tools a company already runs on - Slack, Gmail, Notion, Linear, Jira, Asana and more - learns how the organization actually works, and surfaces the highest-leverage moves: what shipped, who is blocked, and the top priorities for the day. Founded in 2025 by Chloe Samaha and Rene Sultan and backed by Y Combinator's X25 batch, BOND aims to give every founder an executive right hand that used to cost a six-figure salary.
Mesmer
Mesmer is an AI 'chief of staff' for engineering organizations that watches the work itself - code, specs, designs and meetings - to give founders and CTOs a live picture of what is shipping, what is stalling and where the friction is, without pulling teams into more status meetings. Founded in 2025 by three repeat founders out of Origin Financial and Glio, the Y Combinator-backed company pitches itself as 'Cursor for CTOs' and says it has reviewed 70M+ lines of code for customers with a combined valuation north of $3B.
Ambient
Ambient is a San Francisco startup building an AI Chief of Staff - a shared brain for leadership teams that pulls context scattered across meetings, chat, email, and docs and organizes it around the initiatives that matter. Founded in 2023 by Lawrence Coburn, Brandon Catcho, and Taylor McLoughlin, the product delivers daily prep dossiers, secure meeting notes, and red/yellow/green tracking on make-or-break initiatives for CEOs, Chiefs of Staff, and BizOps teams.
